The van der Meer lab studies the interplay between learning, memory, and prediction in rodents performing decision tasks. We record and decode the activity of many neurons simultaneously during behavior to reveal the neural representations and transformations that underlie cognitive processes such as deliberation, inference, and planning. Through a combination of neurobiological and computational approaches, we seek a fundamental understanding of these processes at the level of neural circuits, within and across interacting brain areas such as the hippocampus, striatum, and frontal cortex. We believe that in the long term, this understanding can support sustained innovation in the prevention and treatment of disorders such as addiction and obsessive-compulsive disorder.
What factors determine the content of hippocampal replay?
How do hippocampal sequences relate to behavior in complex environments?
What is the role of oscillations in routing the flow of information in cortico-hippocampal-striatal circuits?
